3.9 Feeder modules
The following feeder modules are currently available to provide the machine with the various com-
ponent types:
3.9.1 Tape feeder modules
– 8 mm SII feeder module
– 3 x 8 mm S feeder module for 01005 components in paper tapes
– 3 x 8 mm SL
a
feeder module from 0201 components in paper or blister tapes
– 12/16, 24/32 mm S feeder module
3.9.2 Other feeder modules
– Linear vibratory feeder, type 3
– Bulk case feeder module
– Surf tape feeder module for 8 mm, 12 mm, 16 mm
3.9.3 Description
These feeder modules can be used to process all components with the most common package
forms, such as bulk cases, stick magazines and taped components.
The most important feature of the modular component feeding system is its great flexibility. For
example, the conveyor increment can be set on the feeder module. Paper and blister tapes can
be processed with the tape feeder modules. A small range of feeder module types is sufficient to
place a large range of component types.
The position detection system on the feeder modules can precisely determine the component
pick-up position. The position detection is carried out automatically whenever the feeder module
or component trolley is changed.
The feeder modules can be quickly and easily changed or replaced, even by unskilled personnel.
PLEASE NOTE 3
Detailed information on the feeder modules can be found in the operating instructions for compo-
nent feeder modules.
a) SL = shutterless, that is without any component cover
